501

<p>what was the answer to the question with three circles with three tangent lines</p>

502

<p>^</p>

<p>6/7</p>

<hr>

<p>For the question that had the parabola and finding a distance a (or k?) , what answer choice did you guys pick?</p>

<p>I forgot what I picked but I rememeber the letter I picked.</p>

503

<p>O_O you mean the one where radius was
x, x/2, x/3
and their total area was pi?</p>

504

<p>did anyone else hesitate longer than normally for the math question that asked you to find an angle between 3 equilateral triangles with a center of O?
it took me a couple tries to come up with the right diagram to solve it
i think the answer was 60 degrees</p>

505

<p>parabola: a + [(b-a)/2)]
and then just simply it till you the answer in terms of what they asked for… don’t remember though</p>

<p>oh wait, i think I got 2a - something … E or something</p>

506

<p>I don’t remember having that equilateral problem.</p>

507

<p>Oh man there was a very tough math question that I skipped…It dealt with a circle and arcs and degrees…the answer was in fraction form. I don’t remember the question lol…but it was very hard. i simply skipped that crap…</p>

508

<p>Didn’t get equilateral either</p>

509

<p>oh, perhaps it was the experimental section because i had 4 math sections</p>

510

<p>Wait, so is it 4/7 or 6/7 for the uphill, downhill problem ? I am confused now</p>

511

<p>Answer was 2k - a.</p>

<p>Plug and chug is all you need.</p>

512

<p>DMOC,</p>

<p>the answer to that parabola one was b=2k-a.</p>

<p>[it asked you to find b in terms of k and a, where a and b were the roots of the parabola and where the line of symmetry was x=k]</p>

513

<p>4/7 for the uphill/downhill one. I’m sure on this.</p>

514

<p>Hmm…</p>

<p>On that parabola one I’m purdy sure the answer was b = a-k or k-a. I can’t remmeber what order… But the parabola/dividing line was on the negative side.</p>

515

<p>Definitely 2k -a for parabola, letter a)</p>

516

<p>i’m quite sure its 6/7…</p>

517

<p>For that one fill in, do I get it wrong if I put the slope as 1 instead of 3/4 and put 5 as my answer? Please say no. :(</p>

518

<p>nyuismydream,</p>

<p>6/7 WAS the answer to a different question. but for the uphill/downhill question, the answer was 4/7.</p>

519

<p>the downhill one, does anyone remember what letter it was for the MC?</p>

520

<p>yeah, can you guys refer to where the exact prompt was posted ? I need to check my result by redoing this problem. I am pretty sure I got this one right</p>
